What decides air shipping cost
No single number sets the cost of an air shipment. Several things work together. The size and weight of the freight come first, because aircraft space is limited and priced by how much room and weight a shipment takes. Distance and the route matter next, along with the service level, from deferred air to next flight out or a charter.
Timing plays a part, since freight that must fly today needs space on a specific flight. The trucking at both ends adds to the total, and so does special handling, such as dangerous goods or oversized pieces.
